I have a lot of cpu* getwork miners runing in a corporate intranet, and connect to my mining prox outside listen in 80port (due restrictions of corporate proxy cant connect to non HTTP ports), and my minprox is stratum to pool. Can´t connect direct miners to getwork pool due nature of ports involved.
*Yes, I know that CPU mining is "not reliable", but with a lot of machines, and not paying for power, I get some uBTCs every day
